MOUNTING r03 nIMLnss EYEGLASSES.

Specification of Letters Patent.

Patented Apr. 9, 1918.

Application filed September 3, 1914. Serial No. 860,022.

To all whom it may concern: I

Be it known that I, WILLIAM W. Farms, I

panying drawings, forming a part of the same, to be a full, clear, and exact descrip tion thereof.

The invention relates to eyeglasses, spectacles and the like, and more particularly to frameless devices of this class, and has for its principal object to firmly secure the lenses and their uniting and supporting parts without the drilling of holes in the lenses that is necessary where the usual screw or rivet form of fastening is employed, or without the forming of indentations or projections or otherwise treating the lens in any manner whatsoever.

A further object ofthe invention is to provide simple, reliable and efficient means for mounting optical lenses which is adapt- Y ed to be quickly secured to the lenses by the application of heat thereto. 1

To these ends the invention consists of the novel combination .and arrangement of parts hereinafter described and more par- In describing the invention in detail reference will be made to the accompanying drawings, in which- Figure l is a front elevation of a pair of spectacles provided with my novel features of invention.

Fig.

a curved shoe 3 arranged to conform to the" curvzit ure of the edge of the lens 1 and pro vided with integral strap-members 4, as

shown in Fig. -1. Each of the strap-members 4 1s preferably comparatively thick and wide at the inner end and gradually tapers in width and thickness toward the outer free end, as shown in Figs. 1 and 2. The shoe 3 is provided upon .the inner surface with an elongated longitudinal recess or cavity 5 in which is platedv or attached a quantity of lacquer or other heat-actuated fastening medium 6.

Each of the strap-members 4 is provided upon the inner surface with a recess or cavity 7, in which is plated or attached aquantity of lacquer or other heat-actuatedfastening medium 8, as shown in Figs. 2

and 5. I

Mountedupon the other edge of the lens 1 is a stud9, which is adapted for the attachment of a temple-bow-such as is used in spectacles. The stud 9 is. provided with a curved sh0e-3 and strap-members 4 of the same construction as thoseupon the ends of the nose-piece. I

In mounting the lens 1 in thenose-piece 2, or in the studs 9, one end is inserted between the, strap-members 4, which have been adjusted to frictionally engage the lateralfaces of the lens,-.until the curved edge engages the inner face of theshoe 3. A small amount of heat, such as the flame of an ordinary match, is then applied to the exterior surface of the shoe 3 and strap members 4-, whereupon the lacquer in the cavities 5 and 7 will flow. As soon as the lacquer commences to flow, the lens 1 is pressed firmly against the shoe 3. and the parts allowed-to cool, whereupon the mountin will be securely fastened upon the lens,

. with. the heat-actuated fastening medium constituting a part thereof, so that'all the Optician or user has to do in securing the mountings upon the lens is to apply'the heat. I

Furthermore, it will be seen that by having the heat-actuated fastening medium located in the cavities, the pressure of the lens against the shoe will not squeeze or force out-any of said fastening medium,. which would be the case if it were applied to the plain surface. -With this constru Q l neearza tion, also, the outer edges of both the shoe andthe strap-members can be br pl lght into close contact with the lens and a perfect joint between the same efiected'.

It Will also be seen that by making the strap-members comparatively thick at their inner ends where they join the shoe-member, any liability or tendency of said strap-members to open or spread when lateral pressure is applied to the lens will be obviated and a firm and strong mounting will be produced.

\Vhat I claim as my invention and desire to secure by Letters Patent is 1. An article of the character described, comprising a curved shoe having an elongated longitudinal recess upon the inner surface and two strap-members extending there'- from.

2.. An article of the character described,

comprisinga curved shoe having an elongated longitudinal recess upon the inner surface of less width than said inner surface, and two straprmembers each having a recess upon its inner surface.

3. An article of the character described, comprising a curved shoe-member having an elongated recess upon the inner surface, a

heat-actuated fastening medium attached to said shoe-member within said recess, and two strap-members formed integral with said shoe-member.

l. An article of the character described, comprising a curved shoe-member having an elongated recess of less width than the inner surface thereof, a heat-actuated fastening medium attached to the surface of said recess, two strap-members, a longitudinal recess in each strap-member, and a heat-actu--- ated fastening medium attached to the surface of each of said recesses.

5. The combination with a lens of a mounting comprising two strap-members and a heat-actuated fastening medium for securing said mounting to said lens.

6. The combination with a lens of a nosepiece provided at its end with a curved shoe having an elongated recess of less width than the thickness of the lens, two strapmembers each having a recess in. its inner surface and a heat-actuated fastening medium for securing said shoe and said strapmembers to said lens.

7. In an ophthalmic mounting, the combination with a strap member in the form of a laterally open box, of a heat actuable adhesive formed on-and adhering to the inner face of the strap, whereby heating of the strap will soften the adhesive to cause it to firmly engage and secure a lens as pressed into the strap.

8. As an article of manufacture, an eyeglass strap comprising a box portion adapted to embrace the lens, and a heat actuable adhesive lining carried by the inner face of thestrap, whereby the strap may at any time be attached to or detached from a lens by simply heating thert- 9. As an article of manufacture, a mount for an ophthalmic lens, comprising having edge engaging and side engaging portions for cooperating with the lens, and ahardencd adhesive adhering to and lining the strap, whereby heating thereof will soften the same. to a condition to satisfactorily adhere to and secure a lens within the strap, substantially as and for the purpose described.
